To all whom t may concern:

Be it known that I, JOHN L. Asnnnsfr, a citizen of the United States,residing` at Havana, in the county of Mason and State of Illinois, haveinvented certain new and useful Improvementsin Grain-Drills; and I dohereby Figure l represents a sectional side elevation of a grain-drillembodying my improvements. Figs. 2 and 3 are similar views of modifiedforms. Fig. 4 is a detail perspective view of one ofthe means used tooperate the front frame. Figs. 5 and 6 are detail views.

This invention relates to improvements in grain-drills; and it consistsin the novel features of construction, arrangement, and combination ofparts, as more fully hereinafter set forth and claimed.

The drill-frame consists of two parts, A B, hinged together at (t, theformer being sup` ported by brackets attached to the axle C, providedwith the press-wheels c,whieh latter run in the rear of the runners D,connected with the frame B, the latter being provided with the hopper Eand grain -spout e, oi' known construction. The seed is discharged fromthe hoppers by any suitable connections between the axle C and shaft F.rlhese parts are of well-known construction and arrangement, and need nofurther description.

The runners D are pivoted at their forward ends between ears Q,dependingfrom the under side of a plate-bar, G, and are provided at their rearends with a grain-boot, H, which has integrally cast therewith on itsforward side, preferably near or at the top,a flange, h, to which therear end of the bar G is secured by bolts or rivets. The forward end ofthe rod or bar G is pivoted between castings b, attached to the underside of the front crossrod of the frame B. Cast integral with the shoeon its rear side, and near the lower end thereof, is a lug, il, and onthe rearv side of the hopper, near-rits top, is secured the lug orbracket j.

lis a rod passed through said lugs, and provided at its top above thebracket j with a nut, 7c, while at its lower end it is furnished withtwo adj usting-nuts, one above and the other below the lng t', as shown.

.I (see Fig. l) is a coiled spring encircling said rod, and held thereonbetween the lug t' and bracket j on the hopper, and the upperadjusting-nut resting on the lug@ of the shoe. The object of this springis to force the run ner into the ground, and still, assisted by itsyielding connection with the frame, as shown, allow it to yield upwardwhen meeting with an obstructionas arock, for instance-the rods, andconsequently the runner, being limited in its downward movement by anut, k, on the rod above the lug or bracket j.

Instead of using the spring just described, I may dispense with it anduse the rodfor the purpose of gaging the runner in its downwardmovement. In this construction I use a cross-piece under the bars thatholds the runner true, and secure each end tothe side bar of the frontframe, and apply weights of equal amount on each runner to force theminto the ground the required depth. Of course the amount of weight to beused will depend upon the condition of the ground; or I may dispensewith the rods altogether and suspend from the hopper or side bar of thefront frame a curved hook, K, which embraces the bar G, as shown in Fig.2, thus limiting the downward movement ot' the runner.

L is a gage fixed on the rear side of the hopper, and M is a wedgeinserted between said gage and the front cross-bar of the frame A, asshown in the same figure.

The seat-frame N is connected at the forward end with the rearcross-beam of the frame B by a pivotal connection, not showin) and therear end is supported on the rear erosspiece of the rear frame, A, bymeans ofthe pivotal rod O. The seat Z slides in the slot m in the topbar of the seat-frame for the lpurpose of assisting the driver inforcing the runners into the ground or raising them out of the same.

To the rear cross-beam of the front frame is securely fastened twobars,PP, extending backward and forming extensions of said frame. These barsextend nearly to the axle C, and are provided at their rear ends withholes n.

Q are treadles or foot-levers, connected at their forward ends with thebars l? P by links R, both the links and treadles being provided withholes, as shown. I have shown two forms of connecting these treadles. InFig. 1 I show them as attached to the rea-r cross-beam of the frame A,while in Figs. 3 and 4 I show them as provided with hinge-blocks S,sleeved on the axle of the press-wheel; but I consider either one ofthese forms as the equivalent of the other. By applying weight on thefront end of the treadles they act as a double lever 1 to force therunner into the ground, and by applying weight on the rear end they actin a reverse manner and throw the runner out of the ground, as will bereadily understood. These movements are easily governed by the driver,who, by sliding his seat forward or back and placing his feet on eitherthe front or rear end of the treadles, can lower or raise the runners,as occasion may require.

To assist the weight of the driver in raising the front part of thedrill, I provide a handlever, T, which is substantially L-shaped, withthe horizontal part U sleeved on the axle C, and its free end bearingunder the extension of the front frame, as shown in Fig. 2. s is a rodbracing and strengthening said lever.

From the foregoing description the operation will be readily understood.The runner opens the ground, the seed is fed from the hopper throughspout e and boot H into the furrow made by the runner, and is covered bythe press-wheel c, which. follows directly in the path of the runner,the pivotal connections between the shoe and runner and the frameallowing the ruimer toadjust itself to the'unevenness of the ground.

The drill-frame being formed of two sections hinged together, and thehopper connected thereto, renders it yieldingly supported by theframe-that is to say, the frame being composed of hinged sectionsenables it to yield, and also the hopper which is carried with it,although rigidly connected to the frame.

It is evident that the treadle or foot-lever and the L-shaped hand-leverare equivalents of each other, both serving the same purpose, andconsequently either one may be used, as circumstances may require.

Having thus described my invention, what I claim as new, and desire tosecu re by Letters Patent, is-

1. In a grain drill, the combination, with the frame thereof formed intwo parts hinged together, of a plate-bar, boot, and runner, the latterbeing pivoted at its upper end to said bar, which in turn is pivoted orhinged to the front end of the frame and connected to the boot,substantially as and for the purpose set forth.

2. In a grain-drill, a hopper yieldingly supported by the frame thereof,a runner pivotally connected at its upper end to said frame, a bootconnected to the runner, in combination with the means described forraising and lowering the runner, substantially as and for the purposespecified.

3. In a grain drill, the combination of a frame formed of two hingedsections, having at its front end downwardly-depending lugs, a plate-barpivoted at its forward end between said lugs, a boot connected-to oneend of the bar and provided with a runner, the latter being pivotedbetween ears or lugs depending from the bar, substantially as and forthe purpose described.

4. A grain-drill having its frame formed in two hinged sections, ahopper supported thereby, a boot, and a runner pivotally connected atits upper end to a plate-bar, the latter being connected at one end tothe boot and at its opposite end pivoted to the forward. end of theframe, a rod connecting said boot and hopper, a spring coiled around therod, and means for regulating its tension, substantially. as and for thepurpose set forth.

5. In a grain drill, the combination of a frame formed in two hingedsections, a runner and boot connected together, a plate-bar pivoted tothe forward end of the frame and also pivoted to the runner andconnected at its rear end to the boot, and an operating-lever controlledby the driver for raising and lowering the front portion thereof,substantially as and for the purpose specified.

6. In a grain-drill, the frame thereof formed in two hinged sections, incombination with a treadle or foot lever hinged on the axle of the presswheels, the forward ends having perforations therein, an adjustable linkconnecting the treadle with the perforated end of bars formingextensions to the forward section of the frame, substantially as and forthe purpose set forth.

7. In a grain-drill, a frame formed in two hinged sections, one of saidsections carrying the hopper, the grain-boot and runners connectedthereto and together by a pivoted platebar, and a rearwardly extendingperforated bar, the other hinged section having a treadle or foot-lever,perforated at its forward end, connected to the perforated bar by anadjustable link, and a sliding seat to operate in connection with thetreadle or foot-lever, substantially as and for the purpose specified.

8. In a graindrill, the combination, with the frame and hopper supportedthereby, and the boot and runner pivotally connected thereto, of a lugon said hopper and a'lug integral with said shoe, a rod passed throughsaid lugs, and adjusting-nuts, one on either side of the lug on theshoe, as and for the purpose specied.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
